<h3>ALOS Deskewing Operator</h3>



<p class="MsoNormal"><span lang="EN-US">For ALOS L1.1 data, the annotated times are
not zero Doppler times, i.e. the data is distributed in squinted geometry.
Therefore, the data generally needs to be deskewed to transfer the data into a
zero Doppler like geometry before applying standard SAR processing. </span></p>


<p>Note: For ALOS-2 products, deskewing is not needed because products are already in zero Doppler geometry.</p>

<p>The following
    parameter is used by the Operator:<br>
</p>

<ol>
    <li>Source Bands: All bands (real or virtual) of the source
        product. You may
        select one or more bands. If no bands are
        selected, then by default all bands will be processed.
    </li>
</ol>
<br>

<p>Below is an example of a deskewed ALOS product in which <span style="font-size: 10pt; font-family: Arial;" lang="EN-US">all the pixels </span><span style="font-size: 10pt; font-family: Arial;" lang="EN-US">have been adjusted </span><span style="font-size: 10pt; font-family: Arial;" lang="EN-US">to a more zero Doppler
like geometry. Notice the gap along the top of the image.</span>
